Visual Language brief: 'book works'

This brief revolves around the 'Hot dog fold'.
So first I was trying to get to grips with its general folded design.

To begin with you fold the (this is A4 but other sizes also work) paper in half then in half again.  You then fold in the opposite direction once.  After this you cut down the centre of the page along the fold, leaving once folds height at the top and bottom.  Hold the paper landscape and push together so that the fold in the centre pushes to the back, it will now look like an A5 sheet of paper- fold it from top to bottom and it is complete.  There should be 8 leaves including the front and back.
